Cursor IP Indemnity and GPL Code: What Contract Protection Covers and What Remains

What an indemnity is, and what it is not

An IP indemnity is a contractual promise by a vendor to defend or compensate a customer for specified third-party claims, subject to stated conditions. It is a form of risk transfer. It does not change what code a model suggests, and it does not stop that code from entering a repository.

For procurement, the practical consequence is that the clause itself matters more than the marketing around it. A product page, a sales deck or a webinar statement may describe coverage in broad terms. The binding position is whatever the executed agreement, its order forms and the documents it incorporates say. Counsel should confirm which statements form part of the contract.

NIST's draft Generative AI Profile points the same way. It recommends that contracts and service agreements specify content ownership, usage rights, quality standards, security requirements and content provenance expectations, and notes that third-party agreements may include generative AI-specific indemnity clauses. Those headings make a workable skeleton for a procurement review.

Two contract layers: the tool vendor and the model provider

An enterprise using Cursor has a contract with Cursor. The models behind it are operated by other companies, and some of those companies publish their own IP indemnity programs. These are separate instruments with separate wording. A program written for customers who buy directly from a model provider does not automatically extend to customers who reach the same model through another product. Whether it does depends on the provider's own terms.

That creates two questions. First, does the tool vendor's indemnity apply regardless of which model is selected in the editor? Second, if the vendor's coverage depends on a provider's program, does that program's wording reach you?

Indemnity programs of this kind commonly carry conditions. Typical examples are that a code-matching or public-code filter must be enabled, that output must be used unmodified, that the customer must not have known or should not have known the output infringed, and that certain claim types are excluded. Caps, notice deadlines and control-of-defence requirements are also common. Any of these can narrow practical coverage, so each condition should be recorded and mapped to a setting or a developer behaviour your organisation can actually control and demonstrate.

Why indemnity does not settle GPL obligations

Copyleft licences such as the GPL family attach conditions to the use and distribution of covered code. In general terms, the obligations that matter most arise when a covered work is distributed: providing corresponding source and licensing the combined work on compatible terms. Whether a given piece of generated code is a derivative of licensed code, and whether it is combined with other code in a way that triggers those duties, are legal questions that depend on the facts and the jurisdiction. Qualified counsel should answer them.

A monetary indemnity addresses money: defence costs and damages. A GPL problem can instead present as an obligation, such as a demand to release source for a product, or a need to remove or rewrite code before a release can ship. Those outcomes are operational and commercial. A payment from a vendor may not undo them, and the clause may not promise to try. This is why the question about non-monetary remedies belongs on the checklist above.

There is also a timing problem. A claim or demand typically arrives after the code has been merged, built and possibly shipped. By then, remediation means finding every place the code landed, which is slow without a record of where it came from.

Controls that act before code merges

Because indemnity is a remedy and not a control, the remaining exposure has to be managed earlier, at the point where a suggestion becomes part of a codebase. Two capabilities do most of the work.

The first is code provenance: knowing the origin and licence context of code. For a suggestion, that means being able to tell whether it matches code under a copyleft licence and what the licence terms are. Provenance also gives you something to hand to counsel when a question arises later.

The second is policy enforcement in the execution path. NIST describes content filtering as inspecting information as it traverses a boundary and determining whether it meets a predefined policy. Applied to coding assistants, the same idea becomes a licence policy with three outcomes: allow code with no licence concern, redact or strip material that should not pass, and block code that matches a disallowed licence class. Enforcement at that point is enforced at runtime, not reviewed after the fact.

There are tradeoffs. Licence detection is probabilistic, so policy needs tuning to avoid blocking acceptable code or missing short matches. Blocking adds friction for developers, so many teams start by allowing and recording, then move specific licence classes to block. Vendor-side settings such as a public-code filter, where offered, are a useful first layer, but they sit outside your own evidence trail and may be a condition of indemnity eligibility. Your controls should complement them, not replace them.

Where a runtime layer fits

Trussed is a runtime layer for regulated enterprises that need to show what their AI was allowed to do and what it did. It enforces policy in the execution path across models, agents, tools and coding assistants, with allow, redact, block, rate limit and escalation for human approval, applied to individual interactions and tool calls.

For licence risk, Trussed provides code provenance, covering the origin, licence and security context of code, and produces audit-ready evidence from enforcement decisions. That evidence can support a procurement or legal file alongside the contract, and it can show which licence policy applied to a given suggestion. Trussed can be self-managed in the customer's cloud, with configurable retention and data residency.

Trussed does not replace the vendor's indemnity and makes no statement about what any vendor's terms cover. It addresses a different part of the problem: the code that enters the codebase, and the record of how it was handled.
